ART OR PROCESSOF REMOVING SCALE FROM WIRES, RODS, &c.

SPECIFICATION forming part of Letters Patent N0. 781,078, dated January31, 1905. Application filed July 15, 1903. Serial No. 165,567.

To all whom 712; may concern:

Be it known that I, AROHIBALD B. LEG- NARD, a citizen of the UnitedStates, residing in VVaukegan, in the county of Lake and State ofIllinois, have invented a new and -useful Improvement in the Art orProcess of Removing Scale from Wires, Rods, &c., of which the followingis a specification.

My invention relates to improvements in the art or process of removingscale from wire,

rods, and other steel or iron articles.

Heretofore in wlredrawing-mills 1t has been customary to remove thescale from the tinuously, rapidly, and cheaply done.

My improved process or method of removing scale consists in'subjectingthe wire, rod, or other article from whichthe scale is to'be removed toa sharp or short bending operation, which crinkles and loosens thecoating of scale on the surface of the rod or,wire. This short or sharpbending of the rod or wire may be most conveniently effected as the rodor wire is drawn continuously along from one reel or spool to another bypassing it over, around, or between one or more rolls of small diameter.In operating upon ordinary wire rod used in wiredrawing I ordinarilyprefer to pass the wire rod around a small roll, preferably about aninch and a half in diameter, although its size may be varied. Inoperating upon rods of larger diameter or of different cross-sectionthan round or circular the sharp or short bendingand crinkling operationmay be most conveniently effected by passing it between two, three, ormorerolls placed close together, so that the rod or other article isgiven sharp or short bends as it passes between them.

Although my invention may be successfully practiced and the scaleremoved or loosened around the whole circumference of the rod or wire bypassing it around or between a roll or rolls whose aXisor-aXes are in ahorizontal or same plane, the operation is rendered somewhat moreeffective and complete by also causing the rod or wire to pass aroundorbetween a second roll or set of rolls whose axis or axes are in avertical or different plane from the rolls around or about which it isfirst bent. This insures the crinkling and loosening of the scale at allpoints of the circumference of the rod or wire, and is speciallydesirable in operating upon rods, wires, or other articles with a squareor other cross-section than round. fter the coating of scale on thesurface of the rod or wire has thus been crinkled and loosened bysubjecting the'rod or wire to short sharp bendings in one or moredifferent planes the rod or wire is subjected to a brushing operationwhich leaves the surface bright and clean. The rod or wire as it isdrawn along may then pass through a weak solution of dilute sulfuricacid to still further brighten and clean it and perfect the operation.

In the accompanying drawings, forming a part of this specification, Ihave, to enable my invention to be more readily and clearly understoodby those skilled in the art, illustrated an apparatus suitable for usein practicing my invention. v

In said drawings, Figure 1 is a plan View of such apparatus. Fig. 2 is adetail elevation,

partly in vertical section.

erated upon is placed, and C is the take-up drum orreel furnished with adriving gear or pulley O for revolving the same and drawing the rod orwire along continuously. i

. D and D are small rolls, preferably arranged at right angles to eachother, one horizontal and the other vertical, around which the wire orrod B passes as it is drawn or fed forward from the drum A to the drum Cand by which the rod-or wire is subjected toshort or sharp bends in twodifferent planes and the coating of scale thereon crinkled and loosenedby the short or sharp bends produced in the rod or wire as it passesaround these rolls. This sharp bending. or crinkling operation loosensthe scale and causes it to drop off or to be readily removed by therotating brushes FF, which are preferably Wire-bristle brushes. Thesebrushes are driven or rotated through the pulleys f. The bending orcrinkling rolls D D may simply be idlers and are caused to rotate by therod or Wire passing around them as it is drawn forward from thefeed-drum A to the take-up drum C. After being acted upon by the brushesFF the rod or wire, Which is noW substantially bright and clean and freefrom scale, may be passed through a Weak solution of dilute sulfuricacid G in the tank or vat G, in Which the rod or Wire is immersed as itpasses continually forward by the deflecting-rolls g g.

I claim 1. The method or process of removing scale from Wires or rodsconsisting in coiling the same around a roll of small diameter as itpasses continuously from one spool or reel to another and therebysubjecting it to short sharp bendings and crinkling and loosening thescale from the surface of the wire or rod, substantially as specified.

2. The method or process of removing scale from Wire or rods consistingin coiling the same around a roll of small diameter and around a secondroll of small diameter in a different plane, and thereby subjecting itto short sharp bendings and crinkling and loosening the scale from thesurface 01. the wire or rod, substantially as specified.

3. The method or process of removing scale from wires or rods consistingin coiling the same around a roll of small diameter as it passescontinuously from one spool or reel to another and thereby subjecting itto short sharp bendings and crinkling and loosening the scale from thesurface of the Wire or red, and then subjecting the wire or rod to abrushing operation, substantially as specified.
